This paper presents system for communication between sensors and central unit using power lines. The system is intended for wide range of applications in which it is needed to collect data from several sensors connected by two-wires only. The wires provide power to these sensors and at the same time transfer the data. The paper describes hardware and software implementation of the parts of the system - the receiver unit, the sensor transmitter unit and programming unit - and also the communication protocol which is used.
